Trouble connecting Pay Pal to Squarespace

[greta9]

Hello,

I have been getting this error

{"error":"Could not find the requested ExternalAuthenticationRequest with name: eubCh7ko4DiEXF_o-oMgCvZbEAJsOV-ttLcpJ5kJ","notFound":true}

Trying to connect my Squarespace to my Pay Pal, I get through the whole process and then this is what the last page says
